Improvement in sash-holders



- anatema JOHN r.zAcnAn1As, or Lausanne, vIRer'NIA.

To4 all zvhomit may 'concern Be it `known that I,.JoHN F. ZACHARIAS, ofLeesl `glourg, in the county of Loudoun andV State of Virginia,

` `have invented a new and useful Improvement in Sash- .Fastencis;` andI do `hereby `declare the following to be a clear and exactdescription'of 'the nature thereof,

my invention appertaius to fully understand and'use the same, referencebeing had to the accompanying drawing makingpartof this invention, inwhich 'the y `figures are sideviews, illustrating the Various positionsj which the fastener assumes" during manipulation V ythereof.` j

j Similar letters of reference indicate corresponding .parts in the twogures. i i j j This inventiouconsists in a sash astener, construc- 1 tedof segmental arms, mounted on hearings formed `with the face-plate, andhaving `elastic feet, and a spring arranged to act on the center ofarms, as will he hereinafter more fully described. i In the drawing-- jA A represen ts two arms, continuous ofeach other, j and formingsomewhat ot' a segment of a circle. They L are provided with a suitableoperating handle, G. The arms A, in the present case, are pivo'tedtobearings, F, formed with, or secured to, a face-plate, I3, which hasopenings through which the ends ofthe l arms may protrude, when turnedto the full extent of j i `the directions in which they swing. y Y

To the center ot' the arms I secure one end ot' a i coiled or otherspring, O, whose other end is secured t `to theface-plate B. I prefer toform, on the arms, a projection', D, as a means of attachment for thespring,

but this may be dispensed with, if desired.

j j 'In the ends of the arms Iv attach rubber feet, E, which may be letinto the arms, or'bc cemented, or j otherwisesecuredthereto. i Thefastener is to be set, preferably, iut`oa mortise i in the sash-fram`e,with the handle projecting iu such directions as to be convenientlyreached and operated. .x `,"When the handle isyat or about right anglesto the sash, neither the eudsofthe arms nor the rubhersare i in contact4with `the` window-frame. In this position the `sash may be raised orlowered. Thel operation on the lower sash is as follows: 1 'lhc sashhaving been raised to its full or partial extent, will'be held orsustained by throwing the lever or handle downward, thus bringing thelower arm in 1 vcontact with the sash-frame. The gravity of the sash f`tends to force said arm tightlyagainst the frame,

whereby the sash is rmlyheld. Y

j; `suficient toenable others skilled in the art to which Letters PatentNoi 104,395, dated June `14,' 1870.

yIIMPVIROV'EMEN'T IN SASH-I-IOIIDERS.

The Schedule referred to in these Letters Patent and making part of thesame. A

When the handle is first started, and moved past the center, the springat once acts against the upper arm, and thereby forces out the lowerarm. It thus assists in keeping the arm in place.

It will now be noticed that it' the sash'is only at a z partial height,it may be raised still higher by lifting it, the pressure against theframe being'then released, but it is advisable to bring the handle to aright angle, to preveut'ii'icton between the `rubber and windowframe.

If the sash is to be lowered, the arm must be released v from contactwith theframe. 'N ow lower the sash as far asldesired, and let go the,handle, and `the result is the same as previously stated'.

Then the sash is fullylowered, it is securely locked by throwiugup thehandle, which operation draws in- .the lower arm and forces out theupper arm. The

latter then wedges with the `sash-frame in a ,manner similar to that ofthe. lower arm. j,

, The operation on the upper sash will be in reverse :order to that onthe lower sash.

The segmental arms may be pivoted directly to the sash-frame, either onthe outside, or in a mortise `in side thereof', and a spring be properlylocated to opv The rubbers D prevent injury- -to the wood-work of thewindow-frame, but are not j erate with the arms.

extremely necessary to the operation of the fastener.

The fastener may likewise be connected ,to the window-frame, and operateagainst the sash-frame, but the manipulation and result are notdifferent from that already stated.

The handle of the arms may be of any suitable form,` for convenient andproper operation.

Having thus described my invention,

lVhat I claim as new, and desire to secure by Letters Patent, is

l. The projection D, arms A A, and handle G, formed in one piece, incombination with the open face-plate B and the bearings F, formed iu onepiece,

operating together, in connection with the spring C, substantially asand for the purpose described.

2. 'The arms A A, -mounted on the bearings F, cast or 'formed with thetace-'plate B, the elastic'f'eet E, and spring G, combined and operatingsubstantially as described.

To the above I have signed my name this 4th day `of May, 1870.l
